Hi friend,


To count the word repeating.


import java.io.*;
import java.util.*;
class WordCount
{

public static void main(String args[])
{
String searchStr = "class";
StringTokenizer tokenizer;
try{
// Open the file that is the first
// command line parameter
FileInputStream fstream = new FileInputStream("Filename");
// Get the object of DataInputStream
DataInputStream in = new DataInputStream(fstream);
BufferedReader br = new BufferedReader(new InputStreamReader(in));
String strLine;
//Read File Line By Line
int count=0;
String strval="";
while ((strLine = br.readLine()) != null) {

tokenizer = new StringTokenizer(strLine, " ");
while (tokenizer.hasMoreTokens()) {
strval= tokenizer.nextToken();

if(searchStr.equals(strval))
{
System.out.println("strval " + strval);
count++;
}
}

}

System.out.println ("count" + count);

in.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());
}
}
}
